Whenever I try to run PHPUnit tests with a PHP version less than 8, I get an error like this:
Composer detected issues in your platform:
Your Composer dependencies require a PHP version ">= 8.0.2". You are running 7.4.28.
PHP Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.0.2". You are running 7.4.28. in /var/www/html/w/vendor/composer/platform_check.php on line 24

Error: This version of PHPUnit does not support code coverage on PHP 8
I tried grepping in vendor for >=.*8\.0\.2, and found that symfony/string, symfont/deprecation-contracts, and symfony/var-dumper all seem to have this requirement. I have no idea how Composer works, so I don't really know how to debug further.
